DOUBLE-,SEAMING MACHINE.

JPECIEFEGATIQBT forming part of Letters Patent No. 327,571, dated October 6 1885. Application filed March 6, 1885. Serial No. 157,981. (No model.)

To all whom it may concern:

Be it known that I, ROBERT \V. MAsKE, a citizen of the United States, and residing at Chicago, in the county ofGook and State of Illinois, have invented certain new and useful Improvements in Double-Scanning Machines, of which the following specification contains a full and complete description.

The purposes of this invention are, first, to provide in a double seaming machine means whereby the two parts of the process of folding the seam may be performed by the same set of folder-disks, and without removing either the work or the disks from the machine.

Second. As a means to the accomplishment of the first purpose, it consists in providing means for automatically relieving the rolls or folder-disks from the work at the completion of the first part of the seaming process, and restoring them to position from which they are to be advanced upon the work for the second process.

Third. It further consists in providing means for positively driving both folder-disks, while allowing them to be separated more or less, to accommodate the varying character of the work and to allow the easy insertion and removal of the work.

For the accomplishment of the said several purposes it comprises the following features, viz: first, mounting two disks so that they run rim to rim in a common frame, and providing them with working-flanges adapted to perform the two processes of the folding of the seam, said disks being geared together by gears on the rear ends of their spindles; sec- 0nd, providing a revolving bed on which the work rests, and adapting the frame which sustains the said folder-disks to oscillate to and from said bed sufficiently to clear the work; third, locating the pivot of said oscillating frame at a distance below the plane of the work-bed, whereby the said disks in advancing toward the work move obliquely toward the surfaces upon which they are to act, so that the folding process is initiated at and by the first pressure of the disks on the work before their revolution is commenced,- fourth, providing for the spindle of the lower of said folder-disks one bearing-box pivoted in the frame, and the other adapted to slide vertically in said frame and provided with a spring tending to force it down away from the upper disks, whereby the two spindles and their disks are auto- 5 matical] y moved apart and so retained, except at such time as the operation of other parts of the mechanism shall bring them together in apt time for the performance of their functions; fifth, providing upon the standard to which said oscillating frame is pivoted a rigid spur located so as to form a stop for the sliding bearing-box of the lower folder-disk spindle, whereby as the frame is oscillated to advance the disks to the work the disks are forced to gether, the said box sliding in its bearing toward the upper spindle; sixth, providing, connected to the standard of the revolving workbed, a suitable cam to act against the end of the spindle or suitable shoulder thereon, to force said bed upward by means of a hand lever or crank attached to such cam, whereby the bed may be raised and lowered at will, to bring the work successively into position to receive the prcssureof the proper flange of 7 the folder-disks for the different parts of the seaming process.

Figure l is a side elevation of the machine ready to receive the work. Fig. 2 shows from the same position the work in the machine during thejirst part of the seaming process. Fig. 3 is a vertical section of all parts except the folder-disks, the position being during the final part of the seaming process. Fig. 4. is a horizontal section through the pivot-bear- 8 ing of the oscillating frame. Fig. 5 is an e11- larged detail of the portion of the oscillating frame which has the pivoted and sliding bearings of the lower-disk spindle. Figs. 6 and 7 are vertical sections, respectively, of the sliding and the pivoted bearing-boxes of the lower-disk spindle, the former showing, also, the position relative to said sliding box of the spur on the standard which actuates it. Fig. 8 shows three successive stages of the seam. Fig. 9 illustrates the lines of movement of the disks with reference to the seam at different stages.

A is the base to which the standards which support the working parts of the machine are secured. A is the bed-standard. A? is the folder-disk standard.

ZOO

B is the work-bed; B, its spindle, which bears and revolves in bearings in the bedstandard A. B is the cam by which the bed is raised. B is the handle or lever to operate said cam.

O is the foldendisk frame, pivoted at c on the folder-disk standard A having above its said pivot the bearings for the folder-disks D and E, and below said pivot having the swinging pedal-lever connected by suitable chain or rod to a pedal; (3*.

D is the upper f0lder-disk,having the spin dle D and the gear D and adapted to be actuated by the crank DP.

E is the lower or fluctuating folder-disk, having the spindle E and the gear E meshing withand driven by the gear D of the upper folder disk. The upper-folder-disk bearings are rigidin the bearing-tree 0. Those of the lower disk are shown in Figs. 4 and 5, the rear one, E pivoted by means of the gudgeons e in the bearing-tree c and the forward one, E, sliding'vertically in the chamber 0 in said bearing-tree, said bearing-box E being provided with the spiral spring E located above it in the chamber 0 and tending to force it downward, and so carry and hold the disk E out of contact with the upper disk, D. The chamber 0 opens at the lower side of the tree 0 immediately over the point of a spur, a, on the standard A, and said spur is adapted to enter said opening when the frame 0 descends, and to collide with the bearingboX E, and force it upward in its sliding bearings in the chamber a", rocking the spindle E over the pivots e of its rear pivoted bearing-box, The gears D and E are formed with sufficient play in their meshes to allow the movement described of the lower-disk spindle with-.

out binding or distorting the gears.

The work is prepared for the operation of the seaming-machine, in the usual manner, by folding the edges, one into a lip and the other into a partly-formed hook, as illustrated in position I of Fig. 8, and in that position the two edges are inserted between the folderdisks, which stand in the position shown in Fig. 1. By pressure of the foot upon the. pedal 0 the oscillating frame 0 is caused to swing over and downward toward the edge of the bed B. In this motion the spurais caused to protrude up into the openinginto the chamber 0 and collide with the sliding bearingbox E therein, and arrest its downward movement at the position shown in Fig. 2. The frame 0 and the upper folder-disk continue to move downward, and so moving press upon the open seam formed by the partly-folded edges, which lie between the flange E of the lower disk and the rim d of the flange d of the upper disk, D, and close said seam firmly together, as shown in Fig. 2, and thereupon, rotary motion being given to the disks by means of the crank D and the gears D and E the first process of forming the seam is accomplished in the usual manner. Thisstep in the process being completed, the pressure of' the foot being removed from the pedal, the spring E will force the disks apart, and the cam B being given a quarter-turn by means of the lever E the bed is raised to the position shown in Fig.3, and at the same time the oscillating frame 0 swings back to its original position, the flange e of'the lower disk, E, passing by the folded edge of the seam, which has rested upon it, as it is able to do by reason of the position of the center of oscillation, the pivot 0 being located, as shown, considerably below the plane of the bed B, so that the slight rise'of that bed has carried the edge of the seam above the are described by the edge of the flange, as shown in Fig. 9; The pedal. being again depressed, the frame 0 swings over toward the bed B, its upper disk, D,moving so that its flange (1 describes the are m 00, (shown in Fig. 9,) while the rim d of the flange d describes the are 1 1/. Thus the attack of the rim d upon the partly-formed seam is in such direction as to fold it down over the edge of the bed B, whereupon the flange d advances upon it, and it is firmly pressed into the angle between the flange d and the flange d The position is that illustrated in Fig. 3. Rotary motion being now given to the disks D and E, as before, the seam is completed throughout its entire length, as shown in crosssection 3, Fig. 8, after which, the pedal being released, the disks are separated by the action of the spring E the frame 0 swings back to its original position, and the bed B being lowered by the reverse movement of the camlever B", the several parts are in'their initial positions, respectively, and ready for the repetition of the double process described.

It will be observed that the lower disk, E, is not at right angles to the bed B, and that the working-faces of the flanges of the disk D and the edge of the bed B need not be at right angles to the surface of the bed, but that these angles will be accommodated to the form of the work in which the seam is being turned, being oblique if the angle of the two pieces of the work is oblique, and being either obtuse or acute to correspond to that angle. The gears D and E will be beveled according to the position necessary to give to the disk E. It should be observed, however, that in no case can the disk E be placed horizontal or in plane parallel to the surface of the bed; and my construction should be distinguished from these in which the two disks are placed at right angles and perform the work in a different manner, made necessary by such different arrangement.

I claim 1. In a double-seaming machine, the oscillating frame 0 and the folder-disks D and E, journaled therein, in combination with the work-bed B, vertically adjustable at will to work in conjunction with either of the flanges of the folder-disks, substantially as and for the purpose set forth.

3. In a double-seaming machine, in combination with the bed, the folder-disk frame having the bearings for the spindles of the folderdisks, the folder-disks having their spindlebearings in said frame, and provided with the foldenflanges adapted to compress the seam between them, and between one of them and the work-bed, a bearing for one of said folderdisk spindles adapted to yield toward the axis of the other disk, means for advancing said frame toward the bed, and a rigid stop on the standard located and adapted to arrest the yielding bearing as the frame advances and force the disks together, substantially as and for the purpose set forth.
